What does the Baxi Megaflo E370 fault code mean?
The E370 fault code on a Baxi Megaflo indicates a problem with the condensate trap, which may be blocked or malfunctioning. This can prevent proper drainage of condensate, leading to potential boiler shutdown.
Common Causes
- Blocked condensate trap: Debris or sludge accumulation can obstruct the flow of condensate.
- Faulty trap mechanism: The internal components of the trap may be damaged or worn, preventing it from functioning correctly.
Can I fix it myself? (DIY)
It is advisable to call a Gas Safe Engineer to address this issue, as working on gas appliances can be dangerous. Attempting to fix it yourself may void warranties or lead to further complications.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an E370 fault could be around £150 to £250, depending on whether the condensate trap needs cleaning or replacement. This includes parts and labour for a qualified engineer.
